The invention provides a test system for simulating intermediate hydrogen removal separation effect in electrolytic chlorine production. The test system comprises a circulating water supply system, a pressurizing and air dissolving system, a first electrolytic chlorine production device, an intermediate hydrogen removal device and a drainage gas collection device, and the circulating water supply system comprises a circulating water inlet pipeline, a circulating water tank, a circulating water pump and a first ejector; and the pressurizing and air dissolving system comprises an air compressor, an air dissolving tank and a pressurizing pump. According to the test system for simulating the intermediate hydrogen removal separation effect in the electrolytic chlorine production process, seawater in the circulating water tank is pressurized and pumped into the dissolved air tank by using the pressurizing pump, and air is conveyed into the dissolved air tank by using the air compressor, so that the air is dissolved in water to form dissolved air water, the process of generating hydrogen during electrolytic chlorine production and the air-liquid mixed flow state of an electrolytic solution are simulated, and the air-liquid separation effect of the intermediate hydrogen removal device is conveniently verified.

Description

technical field [0001] The invention relates to the technical field of gas-liquid separation, in particular to a test system for simulating the effect of hydrogen removal and separation in the middle of electrolytic chlorine production. Background technique [0002] Sodium hypochlorite sterilization technology is widely used in the disinfection treatment of circulating cooling water in coastal power plants and ship ballast water. At present, the method of electrolyzing seawater or brine to obtain sodium hypochlorite solution is mostly used for on-site preparation. During the electrolysis process, hydrogen gas will be generated, and hydrogen gas is a by-product of the electrolytic chlorine production process. On the one hand, it is flammable and explosive. The gas needs to be quickly discharged out of the electrolytic chlorine production device; on the other hand, for large-scale electrolytic chlorine production equipment, with the progress of the electrolysis process, the ac...

Problems solved by technology

[0003] In the prior art, when testing the gas-liquid separation effect of the intermediate dehydrogenation device, due to improper hydrogen collection methods or poor sealing of the test system during the test, etc. , there will be a potential explosion hazard

At the same time, the intermediate hydrogen removal device of large-scale electrolytic chlorine production equipment needs long-term operation to test its gas-liquid separation effect. Long-term operation of electrolytic chlorine production equipment, first, consumes a lot of energy, and second, requires high requirements for the power supply system of the plant area, which often requires coordination Stop production for testing, affecting normal production order

Moreover, the test seawater is often reused. During the test process, as the seawater is continuously electrolyzed by the electrolytic chlorine production device, the content of chloride ions in the seawater after electrolysis gradually decreases, and the amount of hydrogen generated by electrolysis gradually decreases, which cannot effectively verify the intermediate hydrogen removal. The gas-liquid separation effect of the device
